ExcelWin/Mac Scalable Calendar Control

Ease of UseIntermediateVersion tested withWin: 2000, 2003; Mac: XSubmitted by:BlueCactusDescription:A calendar control that runs on both Mac and Windows. Does not rely on ActiveX.

Discussion:The most-employed calendar control uses ActiveX, barring it from deployment on Mac versions of Office. (Macs do not run ActiveX.) This KB provides an alternative. In addition to allowing the user to select dates, it also allows (if desired)for the selection of one or more events (e.g., holidays, meetings) associated with one or more dates.
